Original Abstract Submitted

a turbomachine part has a primary axis and at least one inclined portion extending in a secondary direction forming a non-zero angle with the primary axis. a method for additive manufacturing of the turbomachine part includes the steps of a) for each inclined portion: a1) providing a target roughness of an outer surface of said inclined portion, a2) providing a mechanical weakening of the inclined portion, and a3) determining a maximum roughness of the outer surface of the inclined portion according to the mechanical weakening. the method also includes steps of b) determining a total maximum roughness according to the maximum roughness of the outer surface of each inclined portion, c) determining, according to the total maximum roughness, an orientation of the primary axis of the part to be manufactured with respect to a plane of a manufacturing platen of the additive manufacturing device, and d) producing the part.
